Product Description

Circuit Breaker are widely used in the construction and real estate industry,  the field of industrial manufacturing,  electric power and energy industry, and so on. Circuit breakers, as important protection and control devices in power systems,have the following significant advantages:
1. It has strong overload protection capability,
Automatic overload current cut-off: When the current in the circuit exceeds the rated value (such as equipment failure or excessive load), the thermal elements or electromagnetic mechanisms inside the circuit breaker will act rapidly to automatically cut off the circuit, preventing fires or damage to wires or equipment due to overheating.
Reusable: Unlike one-time blown fuses, circuit breakers can be manually or automatically reset after faults are eliminated, without the need to replace components. This results in lower usage costs and more convenient maintenance.
2. Short-circuit protection is fast and reliable
Millisecond-level response: When a short circuit occurs in the circuit (with a sudden surge in current), the electromagnetic trip unit of the circuit breaker will immediately act, cutting off the power supply within an extremely short period of time (usually within milliseconds) to prevent the short-circuit current from causing devastating damage to the equipment and lines.

 

3. It has both control and protection functions
Normal on-off operation: In addition to fault protection, circuit breakers can also serve as switches for normal circuits, used for manual connection or disconnection of power supply, facilitating equipment maintenance, circuit switching and other operations.
Multiple control modes: Supports manual, electric (such as through relays, intelligent control systems) and other operation modes to meet the automation control requirements of different scenarios.
4. It has a wide range of applications and strong scalabilityHigh reliability and long service life
The current rating coverage is comprehensive: from small household circuit breakers (such as 16A, 32A) to large industrial circuit breakers (up to several thousand amperes), it can be adapted to circuits and equipment of different powers.
Modular design: It can be combined with modules such as leakage protection devices and overvoltage and undervoltage trip units to form multi-functional circuit breakers (such as leakage protection circuit breakers), providing more comprehensive safety protection (such as anti-electric shock and abnormal voltage protection).

 

5.High reliability and long service life
Long mechanical life: The mechanical operation life of high-quality circuit breakers can reach tens of thousands of times or more, making them suitable for scenarios that require frequent on-off operations (such as power distribution systems and motor control circuits).
Maintenance-free design: The internal structure is well sealed, eliminating the need for regular lubricant addition or component replacement, thereby reducing maintenance costs and the requirement for manual intervention.
